Description
Ferrosilicon 75 is an essential element in the steel production process. Widely used as oxygen absorber and alloying element. This alloy is made by reducing silica with coke in the presence of iron. Ferrosilicon, which has a higher silicon content, is produced in sinking furnaces. Typical ferrosilicon formulations contain 70 - 75% silicon of different grain sizes. The specifications provided for ferrosilicon are shown in the table below.
